pH meter: A very complete set for checking the quality of your water, whether from a tap, hot tub, home-brewed water, indoor soil cultivation, aquarium, hydroponics or swimming pool. In addition, pH test pens are small, lightweight and easy to carry when going out!
Wide application: suitable for water quality tests at home and in the laboratory, including drinking water, electroplating baths, aquarium water, swimming pool water, well water, deep diving, aquaculture, food processing and more.
Quick to use: when you press the "HOLD" button, the TDS water tester locks the measurement and automatically switches off after a few minutes of inactivity. The pH tester has an automatic calibration function, so you can quickly get a reading! Avoid measuring solutions with strong acids, strong bases or high temperatures (>50°C), as these may affect the measurement accuracy.
High accuracy: pH meters range from 0.00-14.00 (PH), while digital EC and TDS meters range from 0 to 9999 ppm. The pH resolution is 0.01pH, accuracy ±0.01pH. TDS: 0 - 9999 ppm, conductivity: 0 - 9999 us/cm, accuracy: ± 2%, LCD display with blue backlight for reliable and fast readings. To ensure accurate measurement results, it is recommended to calibrate with a standard pH buffer before first use.
Easy calibration: pH tester automatically calibrates at three points. No tools needed, simply remove the protective cap and dip the pH meter electrode into the solution. Press "ON/OFF" to turn on the electronic pH meter, stir gently and wait a few seconds for the reading to stabilize.

TDS Tester for Hydroponic Base Water - Understanding the pH requirements of specific plants is crucial for optimizing hydroponic systems. Different plants have specific pH preferences and most nutrient solutions generally have a pH value between 5.5 and 6.5. To ensure the stability of the hydroponic system, it is recommended to monitor and adjust the pH value regularly.
PH TESTER WITH HIGH SENSITIVE PROBE - The pH tester has a high sensitivity probe with a resolution of 0.1 and a full measurement range of 0-14 pH. There is also a sponge cap that keeps the electrode moist and thus extends the life of the probe. The easy-to-read display with green backlight allows quick readings in low light conditions and automatically shuts off after five minutes of inactivity to charge the battery
Multifunctional 4 in 1 pH Tester: Our digital GIDIGI pH testers are versatile and can measure not only pH values, but also TDS, EC and water temperature. With a wide test range for pH (0.1-14.0), EC (0-9990μS/cm, 10.01-19.99mS/cm), TDS (0-9990ppm) and temperature (32.0-140.0℉, 0.0-60.0℃), it is perfect for various applications such as hydroponics , aquari, aquari, aquari, swimming pools, tap water, hot tubs and brews.
Display hydroponic pH and ppm value together: our pH tester can simultaneously measure the pH value and ppm of the hydroponic solution. The GIDIGI pH meter helps you know when to add nutrient solution and when to add pH solution to adjust the pH value and ensure the healthy growth of your plants. It can monitor the pH, EC and temperature values of the hydroponic nutrient solution simultaneously on the screen without having to switch buttons.
ACCURATE PH METER WITH EFFECTIVE ATC: Our multifunctional hydroponics pH meter features automatic temperature compensation (0 to 50 C) to ensure consistent readings. The pH EC tester with TEMP function protects sensitive plants and monitors temperature changes to avoid damage and optimise growth. This is essential for hydroponic growers.
